words he said to K-9, cause K-9 to stop. As that crisis is averted June Turner, Gryffen's primary contact with the Department, and Jorjie's mother, arrives to talk about the explosion in the lab, a robot "dog" that was seen in the vicinity near the time of the explosion, and to ask if Gryffen has seen Starkey since his escape. While Starkey and K-9 hide behind a bank of cabinets, June makes it clear that capturing the robot "dog" is a priority of the Department and that she expects Gryffen to find him and bring him in for study. After Jane leaves, Starkey tells Darius that no one has ever stuck up for him like Gryffen has, and Darius agrees that the professor is a great guy. Starkey also thanks Darius for not turning him in. Darius tells Starkey that there will be other times. As Jorjie enters K-9 tells her about nearly "neutralizing" Starkey, and to apologize K-9 gives Starkey a special whistle that will call K-9 wherever Starkey is. Continuity The main K-9 is an alternative to the K-9 Mark I that first appeared in "The Invisible Enemy". "Regeneration" is the first of three parts, the second being "Liberation" and the third being "The Korven". There was a production error when K-9 gives Starkey the whistle, he says that if Starkey blows it, it will "call you to my side." He meant it the other way around: "call me to your side". K-9 informs Professor Gryffen that much of his memory was damaged in his self-destruction, as such K-9 no longer seems to remember The Doctor, whether he remembers Romana and Leela is yet to be seen. K-9 Mark I dies by self-destruction in order to kill hostile aliens and save humans in London; K-9 Mark III met his end in the identical fashion in "School Reunion". Story Notes Before his "regeneration", the K-9 that is seen is identical to the original models used on Doctor Who. According to K-9 creator Bob Baker, this is meant to be K-9 Mark I who was last seen on screen remaining on Gallifrey with Leela. This then implies that K-9 Mark I survived the Last Great Time War. When Professor Gryffen triggers a piece of music stored in K-9's memory, K-9 informs the professor that he cannot name the tune. The 3 notes that are played are the first three notes
